4. Install and configure ntopng

1. Download

Website: http://www.nmon.net/packages/rpm/x86_64 /

wget http://www.nmon.net/packages/rpm/x86_64/ntopng/ntopng-1.2.2-8420.x86_64.rpm

wget http://www. Nmon.net/packages/rpm/x86_64/ntopng-data/ntopng-data-1.2.2-8420.noarch.rpm

2, install

chmod u+x ntopng-1.2. 2-8420.x86_64.rpm ntopng-data-1.2.2-8420.noarch.rpm

rpm -ivh ntopng-1.2.2-8420.x86_64.rpm

rpm -ivh ntopng -data-1.2.2-8420.noarch.rpm

5, configure ntopng

1. View the default configuration file

[root@net1 ~]# cd /etc /ntopng /

[root@net1 ntopng]# ls

ntopng.conf.sample ntopng.start

Note that the ntopng.conf.sample file is a sample configuration file, ntopng .start is the configuration file required for ntopng startup (the ntopng version of the test is empty).

[root@net1 ntopng]# cat ntopng.conf.sample

-G=/var/tmp/ntopng.gid

Note that -G specifies the process used for the run. Number file.

The modified content is:

[root@net1 ntopng]# cat ntopng.conf

-G=/var/tmp/ntopng.pid

--local-networks “10.1.1.0/24”

--interface eth1

--user nobody

--http-port 8888

Note, --local-network “Specify the local subnet segment>; --interface eth1 specifies to listen to traffic on the eth1 NIC; --user z specifies that the account used by ntopng runtime is nobody; --http- Port Specifies that the web service port is 8888. If you do not specify a default of 3000.

6, start ntopng

Note, before running ntopng, to confirm that the redis service is started first, redis provides key value storage for ntopng. We restart the redis service here.

service redis start

service ntopng start

7. Test access

http://IP:8888

Default The username and password are admin.

The above is the introduction of CentOS 6.4 installation ntopng, after installing ntopng, remember to test access, and before installation, you need to configure the yum source and make related backups.
